Omega Manufacturing Division has developed
and formulated special high-performance greases that provide
"extra duty" lubrication under a wide variety of
difficult operating conditions. These Omega multipurpose lubricants
are engineered to outperform ordinary lubricating greases.
Omega multipurpose industrial lubricants
provide:
- Improved machinery performance;
- Elimination of misapplication;
- Simplification of inventory;
- Reduced costly inventory and storage space requirements;
- Versatility of uses;
- Reduced breakdown or production loss time.
Because fewer greases are needed, fewer have
to be bought and stocked. Buying larger quantities of fewer
products bring cost savings in reduced per unit costs. Application
by untrained or semi-skilled personnel is possible and fewer
chances of misapplication are encountered.
Standardization on high quality, extended
performance Omega multipurpose greases allows for the implementation
of automatic grease dispensers or greatly simplified application
procedures using lower cost personnel. Maintenance costs are
reduced as parts last longer and run better and the Omega
lubricant is less prone to squeeze out, burn away, bleed off
or get contaminated.
Field testing was extensive and more than
13,500kg of Omega multipurpose lubricating greases and a selection
of 21 ordinary greases were used to test Omega
85, Omega 33, Omega 77 and Omega 57.
The following are some case histories of
applications where these superior quality Omega multipurpose
lubricants were proven:
High temperature applications
Primary fan bearings of cement kilns
was one application where Omega
85 was tested. Heat from the burner end of
the kiln was radiated to this area and was superimposed upon
bearing-generated heat. The normal temperature for the bearing
using ordinary grease came to as high as 121 oC).
With the application of Omega 85, the temperature
dropped to about 79 oC.
Omega
85 was also tested for lubricating hot oil pumps
where
temperatures reached 204 oC. Asphalt
hot-mix plants require hot oil to be pumped into the mix.
Only greases which will not melt with such high temperatures
will lubricate these pumps. Omega
85 easily withstood these high temperatures.
The bearings of ten fans used in an annealing
oven of a large steel mill were lubricated with ordinary
grease while 10 fans were lubricated with Omega
85 multipurpose grease. Normal working temperature
of these bearings was about 115 oC. After three
months' operation, six fans lubricated with ordinary grease
broke down while those lubricated with Omega
85 continued working for another two years.
Heat with high humidity
Many industries produce under conditions
of both high heat and high humidity. Either of these factors
individually can cause grease to deteriorate. When combined,
ordinary greases cannot provide lubrication for any reasonable
period of time.
In canning factories, where aseptic
conditions are vitally important,
superheated steam is used to sterilize and
evacuate containers, all in one operation. Temperatures up
to 260 oC are encountered and in cooler locations,
moisture from condensation is formed.
Omega
33 was tested in such environments and demonstrated
its ability to handle the lubrication of this equipment.
In the lumber industry, steam is introduced
into the hot air steam that is used to dry lumber in a kiln.
The steam helps control the rate of drying. The centre fan
bearing of this equipment encounters both the heat and the
moisture. Omega
33 multipurpose lubricant was tested in this
application and adhered tenaciously to the bearings and provided
the required lubrication despite the severe and hostile operating
conditions.
In the same industry, the high-speed bearings
in the band saw head rig operate at temperatures above
the boiling point of water. At the same time, the lower bearings
are continuously subjected to the washing action of water
used to cool the saw blade. Another Omega multipurpose grease
- Omega
77 - was used to improve the performance of the saw
band.
Water contamination
Water contamination of lubricants is a constant
source of anxiety for lubrication engineers in almost every
industry. Water interferes with the lubrication process as
well as permitting the corrosion of moving joints. Water can
enter bearings when seals are inadequate or in poor condition
and/or when grease does not adhere to the journal to form
a sealing collar.
In a beer-canning operation, hot water
is usually used to wash down the equipment under high pressure.
The purpose is cleanliness, but the effect on ordinary greases
is the tendency to wash it off the applied part. Water washing
together with contamination with beer, a limited lubrication
reservoir, and, in certain cases, close tolerances, provide
a severe test of any lubricant. Omega
77 withstood all these difficult operating conditions
and provided better lubrication.
Some industries such as sawmills require
bearings to operate submerged. Although designed so that the
bearings would be totally enclosed, this was rarely the case.
The grease is expected to provide the seal against water washing
and admixture in the water. The extremely water resistant
Omega 95 was able to
lubricate under such conditions when other greases could not.
Another successful service test application
was using Omega 57 to lubricate wheel
bearings of mine cars which worked extensively in water
along stretches of many miles of underground tracks.
Newspaper printing presses turn out
a minimum of 28,000 copies per hour and the bearings undergo
a high degree of shearing. In steel mills, large grease
dispensing systems plus high temperatures and high risk of
water contamination is encountered. Omega
77 multi-purpose grease handled these harsh working
environments without difficulty.
Omega multipurpose greases
were found additionally to provide excellent seals and protect
bearings from corrosion and contamination. Omega lubricants
also feature excellent work stability, making high machine
loads at high speeds tolerable. |
